Bardet Biedl Syndrome Protein 4 (BBS4)

BBS4 is a member of the Bardet-Biedl syndrome (BBS) gene family. The similar phenotypes exhibited by mutations in BBS gene family members are likely due to the protein"""s shared roles in cilia formation and function. Many BBS proteins localize to the basal bodies, ciliary axonemes, and pericentriolar regions of cells. BBS proteins may also be involved in intracellular trafficking via microtubule-related transport. The protein encoded by this gene has sequence similarity to O-linked N-acetylglucosamine (O-GlcNAc) transferases in plants and archaebacteria and in human forms a multi-protein """BBSome""" complex with six other BBS proteins. Alternative splice variants have been described but their predicted protein products have not been experimentally verified.
